Coffee Break Training: Sprinklers in Corrosive Environments   [open pdf - 169KB]

"Some harsh environments and chemicals may cause sprinkler operating elements or parts to corrode, potentially affecting the sprinklers' performance or resulting in leaks. According to the National Fire Protection Agency (NFPA) 13, 'Standard for the Installation of Sprinkler Systems', listed corrosion-resistant sprinklers must be installed in locations where chemicals, moisture, or other corrosive vapors sufficient to cause corrosion may occur. Typical locations where corrosive conditions can exist include bleaching operations, dye houses, metal plating processes, animal pens, chemical plants, and salt air environments such as beneath piers and wharves. A not-so-obvious location is this indoor swimming pool where airborne vapors from water treatment chemicals may have a corrosive effect on the Belleville seal that holds back the water as well as the pipe where the sprinkler is connected."
